To all whom t may concern:

Be it known that I, Amann T. NnwELL,

a citizen of the'United States, residing at Birmingham, in the county of Jefferson and StateY of Alabama, have invented certain new and useful Improvements in BailwayTrack Paving, of which the following is a specification.

This -invention relates to paving` between car tracks, and has for its object to provide a construction which will obviate many ofthe' objections incident to Vpaving between Y or along railway tracks.

It is well known that paving along railways is subject to considerable vibration which results in cracking or disintegration of the paving, 1n consequence of which frey quent repairs are necessary. This is a mat- Y and provides means for producing a sub-V stantially continuous paving between tracks, in such manner that it will not be subject to crack or disintegration in consequence of vibration, and a smooth and highly efiicient pavement results.

One form of the invention is illustrated in the accompanying drawings in which Fig. 1 is a plan of such a paving. F ig. 2 is a cross section thereof. F ig. 3 is a. detail in section on the line 3-3 of Fig. 1.

In the drawings, 6 indicate the rails of street car or other tracks. These are set on ties, usually wooden, indicated at 7, in the ordinary manner. To construct my paving between and along the rails I first provide a series of concrete sills or blocks RAILWAY-'Innen ravine.

cated at 11, into which the base of the rail extends, but, preferably, the rails do not rest on these blocks, but are spaced therefrom slightly, as indicated at 12, so that the blocks are not subject to the direct vibration or pressure of the rails, the rails being supported by the ordinary ties. And these blocks 8 are set in the road bed with their topsflush with the central depression of the road bed which receives the paving surfacing. n

This surfacing consists of aplurality of slabs 13. Each slab is of a. width equal to the space between the rails for the inside location, and for the 'outside location similar slabs 14 are used, usually a foot and a half wide to meet the established paving i indicated at 15. The slabs may be as long as desired, but correspond in length to the distance apart of the center lines of the blocks 8, and these slabs are laid between and beside the rails so that they meet above the foundation blocks 8 and rest thereon, as well as on the intermediate ballast or road bed. The slabs are a proper thickness to bring them fiush to the face of the rail, and the central slabs are grooved as indicated at 16 for the wheel flanges.

The slabs may be reinforced with metal rods or the like, and each slab is cut olf at the corners to form a recess as indicated at 17, and one of the reinforcing rods 18 is exposed in the form of a loop 19 at said recess. Each block 8 is provided with a metal eye 2O cast therein, in proper position to register with said recesses when the slabs are laid together on the blocks, and then the loops 19 of the adjacent slabs and the loops 20 of the underlying blocks are tied together by a metal wire tie 21, thus firmly uniting the slabs to each other, and both to the blocks. Grout or liquid cement may then be poured in the recesses to ill the same. Or tar may be poured in, and preferably I use tar to pour in the cracks between the rails and the slabs, this tar flowing down through said cracks and around the base of the rail, where it may ll the spaces 12. The whole forms a water tight paving and prevents the leakage of water through the same into the space under the slabs. Tar is also poured in the cross joints between the slabs.

The slabs may be cast in large numbers in a central plant, and transported to the place where they are laid, and when laid ject to cracking or dislocation incident to vibration, and will be free from the neces- Y, sity of repair, making them superior' to the ordinary means used for paving between tracks.

The invention 1s not limited to the par-- ticular form and proportions shown, but

may be varied in many ways within the scope of the following claims.

I' claim:

l. A paving for car tracks, comprising a series of spaced blocks set in the road bed under the track rails, said blocks being independent of the track ties and spaced ,below the rails and a succession of pre-formed concrete slabs set beside or between the rails and resting on said blocks.

2, A paving for cartracks, comprising a plurality of blocks extending across the road bed under the rails, said vblocks being spaced apart along the track, and spaced below the rails and independent of the ties, and a plurality of pre-formed concrete slabs litting between the rails and restingat their meeting edges upon said blocks'.

` 3. A paving for car tracks, comprising a plurality of blocks extending across the road bed'under the rails, said blocks being spacedV vapart along the track, and a plurality of The tar joints will tend to takeV pre-formed concreteslabs fitting between Vthe rails and resting at ,theirineeting edges upon said blocks, said slabs having recesses at their edges and reinforcing members enposed at said recesses, and fastenings connecting the blocks and said exposed members.

1i. A paving for car tracks comprisinga series of spaced blocks extending crosswise of the track and located underl the rails, said blocks being spaced downward below the rails, and a succession of concreteslabs laid beside the rails and resting at their endsron said blocks.V Y i 7 5. The combination with aA track rail mounted on ties, of apaving comprising' aV at their ends upon said blocks.

6. The combination with a track rail mounted on ties, of a paving comprising a series of spaced blocks set between the ties v and under the rails, and a succession of preformed concrete slabs set beside the rails and resting at their ends upon said blocks,

said slabs having recesses at their meeting recesses, and fastenings connecting theblocks and said exposed reinforcements.

In testimony whereof, I affix my signature.

ALFRED T. NEVELL.
